Ianto's gone longer than he expected, long enough for him to finish coming down and start shivering as he starts to crash a bit. Not because he was too far under, because he wasn't, but even without the D/s element that was a lot more intense, and a lot harder on his body, than he'd anticipated.
The sight of not just painkillers but tea as well definitely perks him up though. Well, that and the novel sight of naked butler!Ianto. "Mmm, that's a sight for sore eyes!" he grins, still a little shakey.
